1 Chronicles 28:9
And you, Solomon my son, know you the God of your father, and serve him with a perfect heart and with a willing mind: for the LORD searches all hearts, and understands all the imaginations of the thoughts: if you seek him, he will be found of you; but if you forsake him, he will cast you off for ever.
